The article presents a construction and testing of a new family of magnetorheological dampers. The work began with testing currently used solutions, which exist inter alia in vibratory machines for example in washing machines. Basis on this job required damping parameters were obtained and then these parameters were used as input data in new devices designing process. A distinguishing feature o...

The methods for preventing earthquake-induced structural pounding between two adjacent buildings include ensuring a sufficient separation distance them or decreasing their relative displacement during seismic excitation. Some equations even specific values of such gap sizes have been introduced so as to avoid collisions. Increasing the stiffness buildings, using tuned mass dampers, applying liq...

The efficacy of dampers in providing seismic protection has been validated by the excellent performance of buildings fitted with dampers in the past earthquakes. However, previous studies have not accounted for the limit states of dampers. Recently, a multi-year research project was completed that investigated the seismic performance of building with dampers subject to large earthquakes. It was...

The main focus of this research has been to investigate the effectiveness of optimal single and multiple Tuned Mass Dampers (TMDs) under different ground motions as well as to develop a procedure for designing TMD and MTMDs to be effective under multiple records. To determine the parameters of TMD and MTMDs under multiple records various scenarios have been suggested and their efficiency has be...

Abstract. This paper presents reviews of several models and numerical simulation models of non-linear and hysteresis behaviors of magneto-rheological liquid dampers in MATLAB®/Simulink® in the example of quarter-car model of vehicle suspension simulation, such as, Bingham, Dahl, LuGre and Bouc-Wen models. In addition, it demonstrates numerical simulation models built in MATLAB®/Simulink® and di...

This paper proposes a vibration model for modal analysis and control of vertical cable-dual tuned mass damper (C-DTMD) coupled system. The proposed introduces several non-dimensional parameters to describe the in-plane Moreover, phenomenon split is comprehensively studied present complex modes. Parameter conducted show influence length ratio, damping frequency ratio on reduction. In addition, t...
